Someone can crush a part of the rock at the bottom of the well, and at the same time, use the shearing action of the sliding belt of the cones to cut the missing teeth. The three-tooth tri-cone drill bit is composed of more than 20 parts and components such as cutting structure, bearing structure, locking element, oil storage and sealing device, nozzle device, etc.

Threaded tricone bit; The number of wheels can be divided into single cone, two cones, three cones and multi-tooth tricone bits.. In the petroleum, exploration and various drilling industries, the toothed tri-cone bit is an indispensable and important part. When the cones roll at the bottom of the well, the teeth on the cones sequentially impact and press into the formation. When the cones are rotating at the bottom of the well, the teeth on the cones hit and press up to the sky in sequence.

The composite sheet can sharpen itself in the process of the task,Metal drill bits Manufacturers that is, after being worn, its front edge will still be blunt. The matrix drill bit is sintered with tungsten carbide powder, brazed on the tungsten carbide matrix with an artificial polycrystalline diamond composite sheet, and gauged with natural diamond. It reduces the cost of drilling for the drilling industry. 　　

There are two types of drill bits: steel body and carcass. The rock breaking method of the drill bit is mainly plowing for soft formations, and shearing for hard formations.

In those two night classes, general diamond drill bits are suitable for formations with relatively low abrasiveness, harder ground, and complex ground; Especially after the emergence of radial tricone bits and long nozzle tricone bits, the drilling speed of tricone bits has increased greatly, which is a serious problem in the history of the development of tricone bits. Rock, so that all rocks at the bottom of the well are broken, and the wellbore can be extended. This has prompted some drilling industries to have a lot of interest in second-hand tricone bits
